Does marijuana use affect the brain? What is the scientific evidence? On this episode, Dr. Anne Speckhard discussed marijuana use and the brain. Topics: science, marijuana, brain, groks Source: Groks Science Radio Show Podcast
Keeping up with the advances in science and technology can be daunting and it would help to have a brain trust. On this program, Garth Sundem discussed the Brain Trust. Topics: science technology, brain trust, groks Source: Groks Science Radio Show Podcast
In April, 2013, the Obama administration unveiled an ambitious plan to better understand the human brain and the causes of its dysfunction. They called it the BRAIN initiative. How can scientists rise to this momentus challenge? What can we reasonably expect in the next few years? Our guest, neuroscientist Partha Mitra, offers background and insight.

That male and female brains are wired differently is simultaneously well-accepted and controversial. In his work, Dr. Ruben Gur, Professor of Psychology at the University of Pennsylvania, has studied functional and anatomical sex differences in the brain. On this episode, we discuss his findings and what they mean for the way we think and how we interact. Topics: gender, sex, neuroscience, brain, psychology, Ruben Gur Source: Groks Science Radio Show Podcast
Is your inclination to socialize linked to your allergies? Until now, human behavior was not believed to be influenced by the immune system; however, recent findings suggest otherwise. On this program, Anthony Filiano discusses how interferon molecule, an immune molecule, is needed to socialize in a variety of different animals. Topics: immune system, social behavior, interferon, brain
How does a biological system, like the brain, give rise to an emergent property, like the mind? Can quantum physics provide the answers? On this program, Prof. Werner R. Lowenstein discussed physics in mind. Topics: science, mind, brain, quantum mechanics, physics, groks Source: Groks Science Radio Show Podcast
Traumatic brain injury can result in the emergence of severe psychiatric symptoms. On this episode, Dr. Sandeep Vaishnavi discussed the diagnosis and treatment of psychiatic problems associated with traumatic brain injury.

Most people would agree that a biological understanding of mental illness is an important effort and, accordingly, it is widely pursued. But how often do you hear about researchers investigating positive qualities such as mindfulness, compassion, and creativity? Today we'll talk with Dr. Richard Davidson, neuroscience professor at the University of Wisconsin and director of the Center for Investigating Healthy Minds. He is widely known for his brain imaging studies of meditating Buddhist monks... Topics: Brain plasticity, Mental health, meditation, Buddhism, compassion, mindfulness, brain imaging,...
This episode we speak with neuroscientist Dr. Sliman Bensmaia. He tells us about his research on touch -- how our hands feel, how our brains process this information, and how this research is being used to design better prostheses.

The brain works by sending signals between cells through the rapid-fire release of neurotransmitters. For the first time, scientists using synchrotron radiation have observed the molecular complexes that facilitates the signaling. On this program, Axel Brunger discusses how the SNARE and synaptotagmin-1 proteins join to trigger communication between brain cells.

Our prior belief of the brain as a static and unchanging organ is being replaced by a new understanding of the versatility of the brain throughout life. Brain plasticity, which involves changes occurring in our brain that allow us to learn and function in response to new experiences, happens not only early in life but also in adulthood, as well as in response to traumatic brain injury. Dr. Michael Merzenich, professor emeritus of neuroscience at the University of California, San Francisco,... Topics: Groks, Groks science show, Brain plasticity, Michael Merzenich, Cognition
Now, more than ever, scientists are able to use brain scanning technology to study a living, functioning, human brain. But what can scientists learn by doing so, and how can they avoid the Four Horsemen of the Brainscanpocalypse? Dr. Dorothy Bishop joins us to talk about the potential, and potential problems, of studies involving fMRI or other brain scanning techniques. Topics: Groks, Science, technology, Dorothy Bishop, brain scan, fMRI, CT, functional magnetic imaging,...
